CodeIgniter - Write file names to database from multiple images - codeigniter

Question

I have an upload form with two file upload fields. I am trying to upload the files, and then write the file names to the same row in a database. I have everything working except the file names get written to their own row. I am guessing it's because I am making two separate calls to the model, but I am not sure how to go about doing it in one call since they each have their own "if" statement.
To make my question clear. How do I write the names of two uploaded files to the same row in the database?
Any ideas would be great. This is the code I am working with. Thanks.
View:
<?php echo form_open_multipart('upload_controller'); ?>
<p>
<input type="file" name="userfile">
</p>
<p>
<input type="file" name="userfile1">
</p>
<p><?php echo form_submit('submit', 'Upload them files!') ?></p>
<?php form_close() ?>
Controller:
if (isset($_POST['submit'])) {
$this->load->library('upload');
if (!empty($_FILES['userfile']['name'])) {
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['max_size'] = '100';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$this->upload->initialize($config);
// Upload file 1
if ($this->upload->do_upload('userfile')) {
$img = $this->upload->data();
$file_name = $img['file_name'];
$this->load->model('upload_file', 'upload_model');
$this->upload_model->upload_file1($file_name);
}
}
if (!empty($_FILES['userfile1']['name'])) {
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['max_size'] = '100';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$this->upload->initialize($config);
// Upload file 2
if ($this->upload->do_upload('userfile1')) {
$img = $this->upload->data();
$file_name = $img['file_name'];
$this->load->model('upload_file', 'upload_model');
$this->upload_model->upload_file2($file_name);
} else {
echo $this->upload->display_errors();
}
}
} else {
$this->load->view("upload_form");
}
Model:
public function upload_file1($file_name) {
$data = array('file1' => $file_name);
$this->db->insert('images_table', $data);
}
public function upload_file2($file_name) {
$data = array('file2' => $file_name);
$this->db->insert('images_table', $data);
}
Database row:
| id | file1 | file2 |

Try like this(if you have the number of files....in your case it is "2" )
$this->load->model('upload_file', 'upload_model');
for($i=1;$i<=$numimg;$i++) //in your case $numimg = 2;
{
if($this->upload->do_upload('File'.$i)) //File1,File2 are filenames
{
$img_data = $this->upload->data();
$images[$i] = $img_data['file_name'];
}
}
$data['Image'] = implode(',',$images);
$this->upload_model->upload_file($data);
at your model:
public function upload_file2($data)
{
$data = array('file_name' => $data['Image']);
$this->db->insert('images_table', $data);
}
That's it.If you want to retrive it from database use
$images = explode(',',$data->file_name);
it will give you an array of image names.
